超声波室内定位系统设计

Design of Ultrasonic Indoor Positioning System

随着科技进步,超声波定位技术在许多场景都有所应用。融合红外测距和超声波技术,设计并实现了一种新的超声波室内定位系统。系统以STC89C52单片机作为主控芯片,由四个悬挂在空中固定位置处的节点和一个在地面二维直角坐标系中移动的节点组成。用户通过记录坐标位置,即可描绘出当前物体的定位信息。

With the advancement of science and technology,ultrasonic positioning technology is useful in many scenarios.In this paper,a new ultrasonic indoor positioning system is designed and implemented by combining infrared ranging and ultrasonic technology.The STC89C52 single chip microcomputer is used as the main control chip of the system,which consists of four nodes hanging in the fixed position in the air and one node moving in the two-dimensional rectangular coordinate system on the ground.By recording the coordinate position,the user can describe the positioning information of the current object.
